Measuring high aspect ratio and composite micro-trenches without damage is critical for advanced microfabrication, yet conventional coherence scanning interferometry often suffers from a low signal-to ...

Surface metrology has to increasingly deal with the presence of sub-micron thick films, which are now being used on products well beyond semiconductor devices. Sub-micron films may be incidental – for ...

Topography becomes more important in quality assurance for manufacturing. This regards the characterization of macro-sized to medium optics and the optimization of a manufacturing process using a ...

This experimental setup – based on coherence scanning interferometry – was developed at INRiM. Fiber sensing systems integrate photonic and optoelectronic components that are matched with fiber optics ...

(Nanowerk News) Optical measurement techniques collecting light intensity in the far-field such as conventional and confocal microscopy or coherence scanning interferometry (CSI) enable fast and ...

The fiber itself is used as a transducer in many fiber optic sensing systems (see the section titled “Fiber Sensors,” in ADVANCES IN OPTICAL METROLOGY, the section titled “Optical Fiber Sensors,” in ...

A technique called plasmonic interferometry helps to detect spatial coherence in 'incoherent' light. A technique called plasmonic interferometry helps to detect spatial coherence in 'incoherent' light ...
